SEAT-SUPPORT. i

To all whom/ it may concern:

i Be it known that we, FRANKLIN F. HALL and RAYMU. ALL, citizens preferably also made of strap iron standlng of the United States, residing at Defiance, in the county of Defiance and State of Ohio, certain new and useful Improvements in Seat-Supports; and we do declare the following to be a full, clear, and exact description of the invention, such asiwill enable others skilled in the art to which it appertains to make and use the same.

his invention is a shifting seat, adapted more especially-for use on a vehicle whose frame is hinged or otherwise constructed so that it tilts laterally from time to time; and the object of the same is to improve the construction of the support for such a seat. This object is carried. out by the mechanism hereinafter more fully described and claimed, and as wherein- Figure 1 is a rear elevation of a threewheel corn planter provided with my improved seat support. Fig.2 is a perspective View of the seat support on a slightly larger scale. Fig. 3 is a sectional detail onthe line 3-3 of Fig. 2. Fig. 1 is a longitudinal section through the seat, on the line 1-4: of Fig. 1.

In the drawings the letters W designate three wheels in the present instance which support a two part frame F and F whose parts are hingedly connected as at H. \Ve have shown this vehicle as typical ofone on which this improved seat support and seat may be used with advantage, and in fact we are using the same thereon at pres-. ent; but we do not wish to be limited to this use of it.

Coming now more particularly to details of the present invention, the seat 1 may be of the pattern ordinarily employed on agricul: tural machines, and it is riveted or bolted at 2 to a strap iron 3 extendinglongitudinally beneath it and provided at its extremities with upwardly opening hooks 4;. These hooks loosely embrace parallel cross bars 5,

on edge, and each cross bar has a raised center as shown in Fig. 2 and depressed ends 6 preferably struck on ogee curves and terminating in forks 7 Set screws 8 may pass through the bills of the hooks into the cross bars 5, whereby the seat proper may be adjusted laterally by moving its have invented shown in the drawings a y links 18, and the lower Specification of Letters ratent. Patented Nov. 24, 1914. Application filed November 10, 1913. Serial No. 800,210.

strap iron 3 to the point most convenient for the driver.

Rising from each part of the frameand by preference inclining slightly to the rear, is a standard 10 which is herein shown also of strap iron standing on edge, and in order to prevent the standard from swinging from side to side it is bracedas at 11. Each standard carries ahead which may be of casting or otherwise, and the head includes a pair of arms 12 standing astride the standard and bolted as at 13 thereto, the arms being slightly spaced from each other and continued to the rear on a horizontal line into a slotted plate 1 1 with the rear end of the slot closed as at 15. On this plate and overlying its slot rests a cap plate 16, and through the same pass the shanks of two eyebolts 17. Their eyes stand beneath the plate 1 1 and are loosely engaged with ends of the latter are pivoted at 19 in the forks 7. These links by preference also are of strap 1ron, and as they fit closely but movably between. the fork-arms, they prevent undue movement forward and backward of the cross bars 5, while theirpivotal connection at 19 therewith and their pivotal support in the eyes of the eye bolts permits the longitudi nal movements of said cross bars transversely of the frame of the machine providing a flexible connection between the seat and frame to permit the frame sections to move transversely relatively to each other. When this seat support is applied to any machine and the same is tilted by reason of unevennesses in the ground, one pair of links swings outward and the other pair swings inward and the entire seat-supporting structure moves slightly toward the lower side. With a three-wheeled running gear as illustrated in Fig. 1, if the intermediate wheel is raised there will be no effect on the seat suport, but if either side wheel is raised the result will be the same as just described. By preference we dispose the links 18 ona slight inclination toward the center as seen in Fig. 1, with the result that any lateral tilting of the machine frame causes the link on the lower side to move downward toward a vertical position while the link on the upper side is retarded in its movement inward to a still more inclined position, for the reason that its lower pivotal point 19 must of necessity rise. If both links stood strictly vertical.

when the frame F i was horizontal, this would not occur. the links 18 with their lowerends converging toward each other, the vehicle to which the seat is applied such as a corn planter-is especially adapted for use in hillside plowing and going around and around a hillwith the machine always at an inclination. When the machine is used for this purpose the seat is adjusted on the cross bars toward the up hill side and when the operator is in position thereon his weight will tend to'f'orce the link on the up hill side downwardly in a vertical position and cause the other link to move inwardly thereby raising the end of the cross bar carrying the seat and which is on the up hill side to properly position the driver. The upper-ends of the braces 11 may be riveted at 20 to the arms of the head, and it is not essential whether these rivets pass through "the upper ends. of the standards 10 ornot. These and other details may be left to the manufacturer, and the materials and proportions of partsare not essential.

hat is claimed as new is:

A seat support comprising parallel laterally-spaced crossbars having ogeeends with Copies of this patent may be obtained for fivecents each;

By this arrangement of r forked terminals, iinkspivotedat one end between said forks, longitudinally slotted plates connecting both-links at opposite ends of said crossbars, the slots of said plates beingyopen at one end and closed at the other,

a pair of downwardly and outwardly inclinedlaterally spaced arms at each end of each of said plates, standards secured between said arms, cap plates, superposed on said slotted plates, and eye bolts, extending through said capjp'la'tes and" theslo'ts in plates on which they are mounted, the eyes of said bolts being disposed, under said slotted plates and loosely engaged with the upper ends of said links, the pair of 'links at one end of said support converging at their lower ends toward the lower ends of the pair of links at the other end of said support when said crossi bars are in normal position.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses. I I
